Be it known that I, RAYMOND G. MOORE, a citizen of the United States,residing at the city of Bridgeport, in the field and State ofConnecticut, have invented certain new and useful Improvements inLatches for Doors; and I do declare the following to be 'a full, clear,and exact description of the invention, such as will enable othersskilled inzthe art to which it appertainsjtomake and usethesame.
